The interesting characteristics of these materials necessarily depend on the porosity: What is not there makes the material what it is. The…

Loops (seen above in blue) between graphene layers can be minimized using electron irradiation (bottom). (Credit: ORNL) According to a press release, researchers at Oak Ridge National Lab have discovered how loops develop in graphene, an electrically conductive high-strength low-weight material that resembles an atomic-scale honeycomb. The nanoscale simulations are bringing scientists closer to using…
